Every household has a screwdriver or two on a shelf in the garage or in the back of a kitchen drawer, but how many times have you not had the right size screwdriver to do the job? Owning a good screwdriver set is an inexpensive way to eliminate the frustration of dealing with stubborn screws around the house. It’s also an invaluable addition to any professional’s toolbox. There are many types and brands of screwdriver sets out there, so how do you choose?
BestReviews has researched the selection, looked at the strengths and weaknesses, and drawn some conclusions. It’s our mission to help you make the right choice when it comes time to buying the best products for your needs, including screwdriver sets.
While there are many types of screwdrivers available, there are just three in common use: slotted (flat), Phillips, and Torx (star).
The slotted screwdriver has been around for a couple hundred years. Slotted screws are cheap and so remain popular. Some people – cabinetmakers, in particular – prefer the appearance of a slotted screw, especially a row of them with the slots lined up. It’s a mark of quality. Unfortunately, it’s easy to twist the screwdriver out of the slot (cam out), damaging the head and making screw removal difficult.
The Phillips-head screwdriver was invented to overcome the issues with slotted screws. Phillips-head screws have a deeper, more positively engaging slot. Locating the screwdriver in the screw is easier, and more torque (twisting force) can be applied. However, too much torque and the screwdriver will slip. It doesn’t harm the screwhead, but it does prevent overtightening.
The Torx screwdriver is the most recent addition, invented in 1967. The screw’s recess is a six-pointed spline, often referred to as a star. Though similar to a Phillips-head screw, these are designed not to cam out. The fit between a Torx screwdriver and screw is more direct, and more torque is transferred. Torx screwdrivers and screws were not widely available at first (the screws are comparatively expensive to produce). As a result, these fasteners were used to make electronic devices tamper-proof. Torx screws have become more popular in industry and manufacturing but remain unusual for household and general-purpose use.
Most of the problems with tightening and loosening screws come from a poor fit between the screwdriver and the screw.
With slotted screwdrivers, the blade should match both the width and thickness of the slot for a snug fit. If the fit is loose, there is a greater chance the screwdriver will cam out and damage the slot. This can also lead to finger injuries.
Phillips and Torx screwdrivers are less likely to damage the head (although it does happen with cheap screws). However, if you use the wrong size screwdriver, you won’t get the proper contact area, making loosening and tightening the screw much more difficult than it should be.
Owning a set that contains many different types and sizes of screwdrivers eliminates the issue of not having the proper tool for the job.
When shopping for a screwdriver set, you need to consider the construction of the screwdrivers and the composition of the set.
Handle: The handle needs to be comfortable to hold yet tough enough to take the battering and mistreatment it will inevitably receive. Hard plastic hexagonal shapes are common on cheap screwdriver sets. They offer lots of strength but aren’t kind to the hands. Modern material combinations can offer durability, a degree of “give,” and excellent grip, too.
Shaft: The shaft needs to be strong enough to resist bending. On low-cost screwdrivers, the shaft is often just steel wire. Better ones use chrome vanadium, which is hard but not brittle. It might flex slightly, but it won’t bend or break easily. Chrome vanadium also resists corrosion.
Blades and tips: These need to be hard or they might deform under torque load. Anyone who’s tried to open a steel paint tin with a screwdriver and had the blade bend has experienced this. High-quality screwdrivers have hardened blades and tips to prevent bending.
Magnetization: Screwdrivers with magnetic tips make it easier to hold the screw in place while turning.
Clip: Some small screwdrivers have a pen-type clip that attaches to the pocket of a jacket or overalls.
Insulation: Insulated screwdrivers have a plastic or rubber sheath over the shaft and handle to protect the user from electric shock if the tool comes in contact with live equipment. While many ordinary screwdrivers have nonconductive handles, it’s no guarantee you won’t get an electric shock. The U.S. Occupational Safety and Health Administration (OSHA) recommends insulated screwdrivers for anyone working with electricity over 50 volts, or for those working in areas where tools might come into contact with conductors or circuits. There are two standards for insulated screwdrivers: 1910.269 and 1926. There should also be a maximum safe voltage rating – 1,000 volts on AC is common.
When it comes to screwdriver sets, the DIYer has a choice of quality or quantity. The range of screwdriver sets is huge, which is great for you, the buyer. Decide what it is you need, fix a sensible budget, and you will almost certainly find the perfect set.
Quantity: Within a modest budget, you might find six or eight screwdrivers in a set from a top brand, or perhaps a dozen or more from a well-known manufacturer that aren’t such high quality. Good, low-cost screwdriver sets frequently don’t include Torx screwdrivers, but homeowners seldom need them. If you do, you can get one for around five bucks, but check the size carefully before you buy.
Quality: Professionals will buy quality screwdriver sets every time. Certain trades have particular needs, so sets are available that only have Torx screwdrivers or that contain all insulated screwdrivers or that have short, palm-fit screwdrivers. If you can think of it, there is probably a set out there! There are also high-quality comprehensive sets that offer great all-round capability.
There are so many combinations available, it’s difficult to be precise about price, but you can expect to pay between $20 and $100 for a set. Try to avoid very cheap screwdriver sets because the handles can be hard and uncomfortable and can shatter, and the chrome plating on the shafts is often poor quality and can flake off easily.
Q. Why do I need screwdrivers of different lengths?
A. In general, the larger the screw, the more torque (turning force) is required to tighten or loosen it. With a longer screwdriver, you generate more torque for the same physical effort. Usually, the longer the screwdriver, the bigger the screw it’s designed to fit. However, sometimes there’s restricted space, which is why some sets often include short, thick screwdrivers as well.
Q. What’s the difference between a wood screw and a machine screw?
A. A wood screw usually has a much more open thread with sharp edges that can cut their own path as they are driven. A machine screw has a tighter thread that doesn’t have sharp edges. The hole the screw is going into needs to have a thread cut into it using an engineer’s tap.
The self-tapping screw is kind of halfway between one and the other. It has an extremely sharp thread that can cut into metal, but only relatively thin steel or aluminum. It’s used for things like metal-framed partition walling, and often for holding the outer panels on home appliances like washers and freezers.
Q. Can’t I just use a small, flat-blade screwdriver on a Phillips-head screw?
A. You could try it as a last resort, but it definitely isn’t recommended. The flat blade won’t go the full depth of the Phillips slot, so you’re not getting proper leverage. This usually leads to the blade slipping. You’ll not only damage the screwhead (making it almost impossible to remove), you could also end up putting the screwdriver through your finger! Buy a decent screwdriver set and you’ll always use the right tool for the job.
